The cmd_find is *either* a frontend looking for particular mailboxes *or* the normal streaming of state change events from the mupdate master to the frontends.  Obviously, there can be timing issues, but the typical paradigm implemented on the frontends is that when an expected mailbox isn't there, the frontend will specifically ask the mupdate master about it using a kick_mupdate().
